Btw, I personally think CCP did a great job on the sound- this is the only game where I feel that having your volume up matters. I can see with my ears as well as my eyes.

Weird, I completely disagree. I too am using the official Sony surround sound headset, and I find the sound design to be particularly underwhelming and immersion breaking.

I'd have to agree with baal here. I to use the Sony Pulse and find the Audio to be somewhat "cartoony" and occasionally off direction.

Not using this as an opportunity to bash the game but in comparison to other Top FPS titles the fidelity is lacking, I'd almost go as far as to say severely lacking. One thing I notice is the volume of gunfire, vehicles etc does not scale well with distance. It's almost as though you either hear it or you don't. While there is some variation in volume based on range it's not nearly as clearly defined as in BF3 for example. Also I find the indoor echo effects to be....well TBH...Disgusting. Like somebody put a cheap cell phone speaker in a tin can disgusting. On top of that every enclosed space in the game that produces an echo effect does so at the exact same volume and frequency of reverberation.

To the OP, Is this the first and only game you've used a headset with? If so, that could be why it seems so impressive. I would encourage you to try out BF3, or really anyone looking for a truly immersive auditory experience.
